What are trust pills? Understanding this combined oral contraceptive

5 min read

Birth control pills are an incredibly effective form of contraception, with perfect use reaching over 99% effectiveness. So, what are trust pills and how do they fit into the world of oral contraception? They are a popular brand of combined oral contraceptive (COC) also used for regulating menstrual cycles and managing related disorders.

Quick Summary

Trust pills are a combined oral contraceptive containing ethinylestradiol and levonorgestrel, along with an iron supplement. They prevent pregnancy by suppressing ovulation, thickening cervical mucus, and altering the uterine lining.

Key Points

  • Combined Hormones: Trust pills contain both estrogen (ethinylestradiol) and progestin (levonorgestrel) to prevent pregnancy.

  • Mechanism of Action: They work by inhibiting ovulation, thickening cervical mucus, and altering the uterine lining.

  • Beyond Contraception: The pills also help regulate menstrual cycles and manage painful or heavy periods.

  • High Effectiveness: With perfect use, the pills are over 99% effective, but typical use is closer to 91-93%.

  • Inconsistent Use Decreases Efficacy: Missing pills or certain medication interactions can significantly lower the pill's effectiveness.

  • Common Side Effects: Nausea, headaches, and breast tenderness are common initial side effects that often improve over time.

  • Not for Emergency Contraception: Trust pills are not designed or dosed for use as morning-after pills.

  • No STI Protection: These pills do not protect against sexually transmitted infections.

Before taking any medication, including combined oral contraceptives like Trust Pills, it is essential to consult with a healthcare provider. The information provided here is for general knowledge and should not be considered medical advice.

What are Trust Pills? A closer look at the components

Trust Pills are a brand name for a type of combined oral contraceptive pill, containing a mix of synthetic estrogen (ethinylestradiol) and progestin (levonorgestrel). This combination is designed to mimic the natural hormones in a woman's body to prevent pregnancy. The specific formulation of Trust pills often comes in a 28-day pack, which includes 21 active, hormone-containing tablets and seven inactive tablets that contain ferrous fumarate, an iron supplement. The iron is included to help replenish iron lost during the menstrual period and serves as a reminder to take a pill each day, maintaining the user's daily routine.

The mechanism of action: How Trust Pills work

Trust Pills function through multiple pharmacological mechanisms to achieve their contraceptive effect. The key actions include:

  • Inhibition of Ovulation: The primary mechanism is the suppression of ovulation, meaning the release of an egg from the ovaries is prevented. The constant levels of estrogen and progestin in the active pills trick the body into believing that ovulation has already occurred, halting the hormonal cascade necessary to release an egg.
  • Cervical Mucus Thickening: The progestin in Trust pills thickens the cervical mucus, creating a barrier that makes it significantly more difficult for sperm to travel through the cervix and reach the uterus. This acts as a secondary layer of protection against fertilization.
  • Uterine Lining Alteration: The hormones also cause changes to the lining of the uterus (the endometrium), making it thin and inhospitable for a fertilized egg to implant. While less likely to be needed due to the other mechanisms, this provides another protective measure against pregnancy.

Key uses beyond contraception

While primarily known for pregnancy prevention, combined oral contraceptives like Trust Pills are also prescribed for various other gynecological conditions. These include:

  • Regulation of Menstrual Cycles: By providing a consistent dose of hormones, the pills can help regulate erratic menstrual periods, making them more predictable for individuals with irregular cycles.
  • Management of Menstrual Disorders: The hormonal balance can help alleviate symptoms of painful menstruation (dysmenorrhea), premenstrual syndrome (PMS), and heavy menstrual bleeding (menorrhagia).
  • Addressing Iron Deficiency: The ferrous fumarate found in the inactive tablets helps combat potential iron deficiency that can be a side effect of regular menstrual bleeding.

What to expect: Efficacy, and side effects

How to take Trust Pills

Proper and consistent use is paramount for the effectiveness of Trust Pills. Users should follow the instructions provided by their healthcare provider and the product packaging. Generally, this involves taking one pill daily at the same time each day. Following the sequence of pills in the pack, including any non-hormonal tablets, is important for maintaining the daily routine.

Efficacy of Trust Pills

Like all contraceptives, the effectiveness of Trust pills depends heavily on correct use. With perfect use, meaning taking the pill at the same time every day without fail, they are over 99% effective at preventing pregnancy. However, typical use, which accounts for missed doses, medication interactions, or other human errors, lowers the effectiveness to about 91-93%. Factors that can decrease effectiveness include:

  • Skipping or missing pills
  • Vomiting or severe diarrhea within 3-4 hours of taking an active pill
  • Taking certain medications, including some antibiotics and anticonvulsants

Common side effects

Many women experience mild side effects, especially during the first few months, as their body adjusts to the hormonal changes. Common side effects of Trust pills include:

  • Nausea and upset stomach
  • Headaches
  • Breast tenderness or pain
  • Bloating
  • Mood changes or depression
  • Spotting or irregular bleeding between periods

Serious, though rare, side effects can include an increased risk of blood clots, heart attack, or stroke, particularly in women over 35 who smoke. It is crucial to consult a healthcare provider for any serious or persistent symptoms.

Important considerations and safety

Contraindications and risk factors

Trust Pills are not suitable for everyone. Women should inform their doctor if they have a history of or current conditions such as:

  • Venous thromboembolism (blood clots)
  • Active liver disease or liver tumors
  • Hormone-sensitive cancers (e.g., breast or cervical cancer)
  • Severe high blood pressure
  • Undiagnosed vaginal bleeding
  • Migraine with aura

Additionally, women who are pregnant or breastfeeding should not take Trust Pills. Smoking, especially for women over 35, significantly increases the risk of serious cardiovascular side effects like blood clots and stroke.

Drug interactions

Certain medications can reduce the effectiveness of Trust Pills. It is important to disclose all medicines and supplements to your doctor. Common interacting drugs include:

  • Rifampicin (an antibiotic)
  • Some anti-epileptic or anticonvulsant drugs
  • Certain antifungals
  • The herbal supplement St. John's wort

Not for STIs or emergency contraception

It is vital to understand the limitations of Trust Pills. They do not offer protection against sexually transmitted infections (STIs), including HIV. Furthermore, they are not an emergency contraceptive (or "morning-after pill"). A dedicated emergency contraceptive requires a much higher dose of hormones than is present in a standard Trust pill.

Conclusion

Trust Pills are a safe and effective option for combined oral contraception, as well as for managing menstrual cycle-related issues, when used correctly under medical supervision. The inclusion of iron tablets helps maintain the daily routine and addresses potential menstrual-related iron loss. However, consistent daily use is critical for high efficacy, and the pill does not protect against STIs. It is essential to discuss individual risk factors, especially for those over 35 who smoke or have certain health conditions, with a healthcare provider to ensure it is a suitable and safe choice. Regular medical consultation is recommended to monitor for side effects and overall health while on Trust Pills.

Frequently Asked Questions

Trust pills contain the synthetic hormones ethinylestradiol (an estrogen) and levonorgestrel (a progestin). The pack also includes inactive pills containing ferrous fumarate, an iron supplement.

No, Trust pills should not be used as emergency contraception. The hormone dose in a standard pack is too low to be effective as a morning-after pill, and a dedicated emergency contraceptive is needed for that purpose.

Trust pills prevent pregnancy by stopping the release of an egg (ovulation), thickening cervical mucus to block sperm, and altering the uterine lining to prevent implantation.

With perfect use (taking it exactly as directed), Trust pills are over 99% effective. However, with typical use, which accounts for human error, effectiveness is around 91-93%.

No, combined oral contraceptives like Trust pills do not protect against sexually transmitted infections (STIs). Condoms are necessary for STI prevention.

If one active pill is missed, take it as soon as you remember. If you miss two or more active pills, consult the package instructions or a doctor. A backup contraceptive, like condoms, is necessary for seven days after consecutive missed pills.

Individuals with a history of blood clots, certain cancers, severe high blood pressure, or liver disease, and women over 35 who smoke, should not take combined oral contraceptives like Trust pills.

Common side effects include nausea, headache, breast tenderness, bloating, mood changes, and irregular spotting. These symptoms often subside after the initial adjustment period.

The inactive pills in a 28-day pack contain ferrous fumarate, an iron supplement. This helps replace iron lost during menstruation and maintains the daily habit of taking a pill to improve consistency.
